ATTORNEYS United States Patent M 3,355,775 PLANETARY COILER HEAD Joe R. Whitehurst, Bessemer City, N.C., assignor to Ideal Industries, Inc., Bessemer City, N.C., a corporation of North Carolina Filed July 21, 1966, Ser. No. 566,870 12 Claims. (Cl. 19-159) ABSTRACT OF THE DISGLOSURE The main rotational components of the planetary coiler are supportingly interrelated by cooperating rollers and trackways for low-friction rotational movement of the components, and wherein the rollers and trackways cooperate to maintain the lower faces of the main components in a common horizontal plane and to prevent relative vertical movement between the components.

This invention relates to a planetary coiler head and, more particularly, to a coiler head adapted to package textile sliver in a stationary receptacle positioned therebeneath by depositing the sliver in a plurality of successive convolutions compacted into the receptacle.

In recent years, textile manufacturers have successfully reduced the frequency of handling packages of materials in process, and the costs attendant to such handling, through the use of larger package sizes. In accordance with this trend, increasingly larger sliver cans have gained usage in the packaging of textile sliver by sliver coilers. While the frequency of handling has been reduced through the use of larger cans, other ditficulties are introduced in that the large diameter cans are difficult to mount and remove from a can table of a conventional coiler and transport of the cans within the mill has become a problem. Attempts to solve the problem of transporting larger diameter cans have been made by mounting casters on the cans, but this merely compounds the dimculty in that caster-mounted cans are still more difficult to mount and remove from a can table.

Planetary coilers have heretofore been known to avoid certain difficulties which have been introduced by larger diameter cans, particularly as planetary coilers do not require can tables. However, such coilers have not heretofore obtained wide acceptance due to their high cost and other deficiencies.

In an additional effort toward packaging greater running lengths of sliver without interruption, textile manufacturers compact sliver coiled into a receptacle so as to pack the greatest possible length in the available can volume. Compacting of sliver into a can requires a vertically directed force on the package of sliver within the receptacle as the sliver is deposited in a predetermined convoluted path to be formed into the package. During the application of a compacting force, those elements of a sliver coiler which overlie the package being compacted will disrupt and distort the sliver package if relative vertical movement of the elements is permitted.

With the foregoing in mind, it is an object of this invention to provide an improved planetary coiler head which avoids the difiiculties and deficiencies described above, by packaging textile sliver in a stationary receptacle positioned beneath the coiler head and compacting the sliver into the receptacle, and which has supporting and drive arrangements which are readily manufactured and assembled, permit high speed operation, and provide other advantages.

A further object of this invention is to provide a coiler head as described above wherein first and second members are mounted for rotation about respective first and second axes, with planar lower surfaces thereof aligned,

3,355,775 Patented Dec. 5, 1967 and supported against relative vertical movement, so that a sliver passage opening through the first member is translated along a predetermined convolute path to deposit sliver passing therethrough in a desired pattern within a stationary receptacle positioned therebeneath and so that sliver deposited in the receptacle is compacted therein.

Some of the objects and advantages of the invention having been stated, others will appear as the description proceeds, when taken in connection with the accompanying drawings, in which:

FIGURE 7 is an elevation view, in section, of a portion of the mounting arrangement for the calender rolls of the coiler head of FIGURE 2, taken substantially along the line 7-7 in FIGURE 4.

Referring now more particularly to the drawings, a textile sliver coiler is there shown (FIGURE 1), and generally indicated at It), which includes a planetary coiler head 11 as comprehended by the present invention. The planetary coiler head 11 is supported by a suitable standard 12 and floor plate or base 13 to which the standard 12 is attached so as to overlie a sliver receptacle or can 14. Preferably, a guide means such as a bracket 16 is mounted on the standard 12 so as to receive the can 14 and assure positioning of the can in the proper location beneath the planetary coiler head 11. In operation of the coiler 10, textile sliver S is supplied to the planetary coiler head 11 and is deposited in the stationary can 14 in a predetermined convoluted path and packaged by being compacted therein. During such packaging operations, the can 14 remains stationary.

Deposition of the sliver S in the required convolute path within the can 14 is obtained by the coil forming rotation of a first member 13 (FIGURE 2) of the coiler head 11 and the coil precessing rotation of a second member 20 of the coiler head 11. The first member 18 has an opening 19 therein for the passage of sliver therethrough and a substantially planar lower surface and is encircled by the second member 20 which has a circular opening therein, within which the first member 18 is disposed, and a substantially planar lower surface.

First support means are provided for mounting the first member 18 on the second member 20 for rotation relative thereto and about a first predetermined axis. The first support means is constructed so that. the planar lower surfaces of the first and second members 18 and 20 are substantially aligned (FIGURE 3) and vertical movement between the members is substantially restrained, for facilitating compacting of sliver deposited in a can by the head ll. Preferably, the support means comprises a first trackway means 21 including a radially projecting bead portion 22, which defines an annular trackway concentric with the circular opening in the second member 20 and is formed integrally with an upstanding rim 24 of the first member 18 (FIGURES 3 and 6). A plurality of circumferentially spaced peripherally grooved rollers 25 (FIGURES 2 and 4) are mounted on the second member 2t) and rotatively engage the bead portion 22 for supporting the first member 18 for rotation while restraining vertical movement of the first member with respect to the second member.

In accordance with this invention, means are carried on the first member 18 for advancing sliver through the sliver passage opening 19. The sliver advancing means comprises a pair of calender rolls 2'7, 23 mounted on the first member 18 for rotation therewith about the first axis and supported thereon for rotation about their horizontally extending axes for feeding sliver through the sliver passage opening 19. Each of the calender rolls 27, 28 is secured to a respective one of a pair of calender roll shafts 29, 3d, and one of the calender roll shafts (namely the shaft 29) is connected by a right angle drive arrangement to a calender roll drive gear 31. The right angle drive arrangement includes a transmission housing 32; suitable bearings 34, 35 within the housing 32 for supporting the roll shaft 29; a first right angle gear 36 fixed to an extremity of the shaft 29; a second right angle gear 38 meshing with the first angle gear 36; and a stub shaft connecting the drive gear 31 to the second right angle gear 38 and mounted Within the housing 32 by an antifriction bearing 39.

In order to impart rotation to the calender roll 27, a ring gear 44) (FIGURES 2 and 3) is fixed to the second member 2% for rotation therewith about the second axis and to overlie the first member 18 and be concentric with the first axis. Upon rotation of the first member 18 about the first axis, the calender roll drive gear 31 is traversed along the internal toothed surface of the ring gear mem ber 49, and the meshing relationship therebetween drives the calender roll drive gear 31 in rotation.

In order to properly grip sliver S between the calender rolls 27 and 28, and to ensure feeding thereof through the sliver passage opening 19 upon rotation of the calender roll 27 as described above, means are provided for mounting the calender roll shafts 29, 34 to urge the calender rolls together While permitting straight line separation movement therebetween to accommodate thickness variation in sliver S passing therethrough. More particularly, a pair of mounting blocs 41, 42 (FIGURES 24 and 7) are provided to mount the calender roll shafts 29, 30 for rotation While permitting separating movement of the calender rolls 27, 28. Each of the mounting blocks (such as the block 41 in FIGURE 7) comprises two segments 44, 45, each of which is penetrated by a respective one of the calender roll shafts 29, 30 and encircles an antifriction bearing 44a, 45a mounting the shaft for free rotation. One segment 44 is penetrated by a pair of counterbored passages 46, while the other segment 45 has a pair of threaded openings 48 therein. Bolts 49 are received within the counterbored passages 45 with spring members 50 encircling the bolts between the heads thereof and the inner end of the enlarged portion of the passages 46. The smaller diameter portions of the passages 46 are sized to closely engage the bolts 4?, which are threaded into the openings 48 of the other segment 44. As the pair of bolts 49 are drawn into the threaded openings 48, the springs 59 are tensioned to bias the calender roll shafts 29, 39 together.

Due to the reduced diameter portions of the countersunk passages 46 and the engagement of those portions with the bolts 49, separating movement of the shafts 29, 30 against the biasing force of the spring is restrained to straight line movement only. Due to the biasing force acting on the calender rolls, 27, 28, it is not necessary to drive the calender roll 28 but reliance may be placed upon the rotation of that roll in conjunction with the rotation of the roll 27.

Upon rotation of the first member 18 with respect to the second member 20, so that the calender rolls 27, 28 are driven to advance sliver S through the sliver passage opening 19, sliver advanced through the opening is formed into successive coils about the first axis.

The first member 18 and second member 2t) are encircled by a third member 51, which functions as a stationary housing for the coiler head 11 and has a circular opening therein and a substantially planar lower surface (FIGURES 2 and 3). Second support means are provided for mounting the second member 2%) on the third member 51 for rotation relative thereto about a second axis parallel to and spaced from the first axis, and for substantially restraining vertical movement between the second and third members so as to facilitate compacting sliver advanced through the sliver passage opening 19 into the can 14. Preferably, the second support means is similar to the first support means and comprises a second trackway means 52 (FIGURE 6) including a radially projecting bead portion 54- formed integrally with the third member 51 and defining an outer annular trackway concentric with the circular opening in the third member 51. Further, a plurality of circumferentially spaced peripherally grooved rollers 55 similar to the rollers 25 mentioned heretofore are mounted on the second member 20 for engaging the bead portion 54 of the outer annular trackway.

Upon simultaneous and coordinated rotation of the first member 18 about the first axis and the second member 20 about the second axis, as described more fully hereinafter, the second member 20 operates to precess the location of the sliver coils which are formed by the first member 18, and to assure that the sliver passage opening 19 is traversed along a predetermined convolute path.

In order to drive the first and second members in co ordinated rotation about the first and second axes respectively, and to translate the sliver passage opening 19 along the predetermined convoluted path of travel, means are provided for engaging the members and connecting the same to a rotative motive means. More particularly, the first member 18 includes an externally toothed surface 6%), located above the first trackway means 21. This externally toothed surface 60 is engaged by an internally toothed surface 61 of a ring gear member 62 (FIGURES 2, 3, and 6) for driving the first member 18 in rotation about the first axis. Third support means are provided for mounting the ring gear member 62 on the second member 20 for rotation relative to the second member and about the second axis.

As illustrated in FIGURE 6, the third support means comprises a third trackway means in the form of an upwardly extending projection on the ring gear 62 which has a radially projecting bead portion 64 defining an upper annular trackway concentric with the second axis. A plurality of circumferentially spaced peripherally grooved rollers 65 mounted on the second member 20 rotatively engage the bead portion 64 to support the ring gear member 62 for rotation above the second member 20 and in driving engagement with the toothed peripheral portion 60 of the first member 18.

Each of the third support means rollers 65 is mounted on the second member 21) by means of a stud arrangement (FIGURE 6). The second member 20 has a number of threaded openings formed therein and a number of studs or standards 91, of a suitable height, are secured to the second member 20 by engagement with the threaded openings. The upper extremity of each standard 91 is provided with a threaded opening to receive a flat headed bolt 92, which penetrates the inner race 94 of an antifriction bearing, and secures the inner race to the second member 20. A peripherally grooved member is fitted onto the outer race 95 of the antifriction bearing, in the form of roller 65, and the peripheral groove thereof is preferably coated with a low-friction plastic material, in order to provide a low friction treatment for one of the rotatively engaging surfaces of the head portion 64 and the roller 65. By careful placement of the threaded openings 90 in the second member, reliance may be placed on the engagement of the conical shoulder of the fiat 5 head bolts 92 with the inner races 94 to properly position each of the plurality of rollers 65.

The first and second supporting means rollers, 25 and 55 respectively, are similarly mounted on the second member through the use of threaded studs similar to the standards 91. The height of the standards employed in mounting the first and second support means rollers and 55 is determined by the spacing of the respective trackway means above the second member 20. Preferably, all of the rollers 25, 55, and 65 are provided with a low friction material coating as described above.

Both the ring gear member 62 and the second member 20 are provided with externally toothed portions 66 and 67, respectively. The externally toothed portions 66 and 67 are concentric about the second axis and are substantially vertically aligned.

In order to simultaneously drive both the first member 18 and the second member 20 in coordinated rotation, gear train means (FIGURE 2) are provided for connecting the externally toothed portions 66 and 67 of the ring gear member 62 and the second member 20 to a common power input shaft. More particularly, for the ring gear 62, the train of gears includes gears 68 and 69 to transmit rotation from a main gear 70 to the ring gear 62. For the second member 29, the train of gears includes gears 71-74 for transmitting rotation from the main gear 70 to the toothed portion 67 of the second member 20. The ring gear member 62 is driven in rotation about the second axis at a higher speed than the second member 20, inasmuch as translation of the sliver passage opening 19 along the desired convolute path necessitates that the first member 18 be rotated about the first axis at a substantially higher speed than the second member 20 is rotated about the second axis.

In order to assure proper passage of sliver S through the coiler head 11 of this invention, to be deposited into a receptacle such as the can 14, and to protect the operating elements of the coiler head 11, this invention provides cover members 76, 77 and 78 overlying the operating elements and a sliver guide means including a trumpet 86 mounted on a cover member for determining the path of sliver to the pair of calender rolls 27 and 28. Two of the cover members, 76 and 77 (FIGURES 1 and 2), are circular members having substantially the same general circular form as the first member 18 and the second member 20, respectively. The smaller circular cover member 76 is secured to the first member 18, as by means of bolts penetrating cover member '76 and secured in studs fixed to the first memebr 18, for rotation therewith about the first axis, while the larger circular cover member 77 is similarly secured to the second member 20 for rotation therewith about the second axis. A generally triangular member 78 extends over the portion of the third member 51 which encloses the gear trains 6844.

In order to guide the sliver S to the calender rolls 27, 28, a sliver trumpet member 80 is mounted in a slidable plate member 81 which in turn is mounted on the smaller circular cover member 76 to overlie the calender rolls 27 and 28. The trumpet member 80 and mounting plate 81 may be adjustable along the nip of the calender rolls in order to obtain variable throw for the sliver coiler head 11.

In operation, the main gear 70 is driven in rotation from any suitable motive means, such as an electric motor or by interconnection to a textile machine, thereby driving the ring gear 62 and the second member 20 in rotation. The ring gear member 62 in turn similarly drives the first member 18 in rotation relative to the second member 20. By the engagement of the calender roll drive gear 31 with the calender roll ring gear 40, the calender rolls 27, 28 are driven in rotation to advance sliver S passing through the trumpet member 80 through the sliver passage opening 19 to be deposited in a suitable receptacle underlying the coiler head 11, such as the can 14. Due to the diiferent rotational speeds of the first member 18 and the second member 20, coils are former generally about the first axis by the rotation of the firs member 18 and the coils are precessed about the secon axis by the slower rotation of the second member 20 As sliver is formed into coils and the coil location; precessed relative to the container 14 a column of slive. builds within the container, occupies the space beneatl the aligned planar lower surfaces of the first, second anc third members 18, 29 and 51 of the coiler head 11, ant is compacted into the can as the same is advanced througl'. the sliver passage opening 19. As sliver is compacted, the vertical compacting force would tend to raise the first and second members 18 and 20 of the coiler head 11, but for the restraint imposed by the first and second mounting means described above. Due to the operation of the mounting means, the substantially aligned condition of the planar lower surfaces is maintained, and disruption or distortion of the sliver during packaging is minimized.
